Possible Causes

Open or shorted NTC sensor, Loose NTC connector, Damaged wiring harness, Control board temperature circuit fault

How to Fix / Troubleshooting

Safety first: Disconnect from mains before accessing internal components.

  • Confirm symptom: Check if the dishwasher completes cycles with cold water or poor drying along with E7.
  • Locate NTC: On Baumatic dishwashers, the NTC temperature sensor is usually mounted in the sump or attached to the flow-through heater body.
  • Inspect connection: Remove the lower panel and locate the NTC. Ensure its connector is firmly attached and free from corrosion or moisture.
  • Check wiring: Follow the harness back to the control board, looking for pinched or damaged wires.
  • Replace NTC if faulty: If you have a multimeter and are competent, test the NTC for a smooth change in resistance with temperature. If open, shorted, or erratic, replace the NTC temperature sensor.
  • Control board: If a new NTC does not clear E7, the control board may be defective and should be assessed by a technician.
